It depends on what you're welding and what kind of weld you need.
For an extremely strong weld where you don't want to transfer as much heat to the surrounding areas, tig is the way to go. Tig has the option of melting only the source material (together), so if it is better than no material is added, then tig is the better process. If you want a small, uniform weld, then tig is also superior.
Mig is wire-feed and so adds material to the pieces being welded. So it is better for filling areas or adding superior strength. If the material surrounding the weld can take the heat or doesn't matter if it is deformed or discolored, then mig welding is the way to go.
A good discussion of Tig and Mig welding is here http://www.ridgecrest.ca.us/~biesiade/weld.htm.
The gist of it is TIG welding melts the metal together and MIG welding uses a filler for the space between to bond the metal.
Aluminum is one example of a metal that cannot be MIG welded and must be TIG welded. The limitation of MIG is usually the heat it can produce versus thickness of the material. One quarter-inch thickness is usually about as thick as you can weld with either MIG or flux-core wire feed welders. Anything else will require the heat energy available with a stick welder.
When we are using the tig welder we getting welding defects on our blanks, but when using the plasma weld no defects are found
Other than being the primary supplier of the Russian air force for fighters and using the same weapons there is no difference. Sukhoi fighters are much larger and more maneuverable while Migs are cheaper. Though in this case you DO get what you paid for.

can weld aluminium with a mig or tig welder
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
Tetanus is a disease that affects the muscles and the respiratory system. The difference between tetanus and TIG or tetanus immunoglobulin is that the latter is a form of preventative vaccine for tetanus.
All three can, but: ARC is the cheapest, fastest and easiest way, but cosmetically poor TIG is the neatest, and slowest, the most expensive, and most difficult to master MIG is the comprimise between the two A weld in any of the three processes will be just as strong as the others.
